Systems are easily configurable to measure different aspects of LED output. The standard system comes with optics for spectral radiant intensity (and luminous intensity in candelas) following the CIE Publication Number 127 recommendations. It can also be coupled to an integrating sphere for total flux measurements, both 2 pi and 4 pi steradians; or a computer-controlled 2-axis goniometer for spatial intensity measurements.

Gamma Scientific offers three models of spectroradiometers for LED testing applications to meet different testing requirements and budgets.
